Thyroid Stimulating Hormone
About the Thyroid Blood Test blood test
The thyroid is a small gland in the neck. It produces hormones that affect many different bodily functions such as your heart rate and body temperature. Having too much or too less of these hormones can cause unpleasant and potentially serious problems that may need treatment.
Our baseline thyroid blood test checks some of the key and central hormones produced by the thyroid gland including TSH, and Free T3 and T4. A high level of TSH and a low level of T4 in the blood could mean you have an underactive thyroid. If your test results show raised TSH but normal T4, you may be at risk of developing an underactive thyroid in the future.

Biomarker information for Thyroid Blood Test blood test
Thyroid stimulating hormone (TSH) is produced in the pituitary gland in order to regulate the production of thyroid hormones thyroxine (T4) and triiodothyronine (T3) by the thyroid gland. If thyroid hormones in the blood are low, then more TSH is produced to stimulate the thyroid gland to produce more of them. If thyroid hormone levels are high, then the pituitary produces less TSH to slow the production of thyroid hormones.
If TSH is too high or too low, it normally signifies that there is a problem with the thyroid gland which is causing it to under or over produce thyroid hormones. Sometimes a disorder of the pituitary gland can also cause abnormal TSH levels.
Triiodothyronine (T3) is the more active of the two thyroid hormones produced by the thyroid gland. Most T3 is bound to protein in the blood. Free T3 measures the level of T3 that is free, or unbound to protein, and is available to regulate metabolism.
Thyroxine (T4) is one of two hormones produced by the thyroid gland. It works to speed up the rate of your metabolism. Most T4 is bound to carrier proteins in the blood – it is only the free, or unbound, T4 that is active in the body. Free T4 is the less active of the two main thyroid hormones. To have an impact on your cells it needs to convert to the more active T3 when your body needs it.
What does the Thyroid Blood Test blood test involve?
This blood test is just like a standard blood test.
You will be asked to uncover you left or right arm and suitable vein is found. A tourniquet will be placed and tightened around your upper arm allowing the veins to swell and a needle will be placed into your vein. A small quantity of blood is then drawn into tubes. Once the procedure is complete a small plaster will be placed onto the site which can be removed after a few hours.
